SHOCK-ABSORBER.

Specification of Letters Patent.

Patented Feb. 16, 1915.

Application filed July 13, 1914. Serial No.850,688.

To all whom it may concern:

Be it known that 1, JOHN A. HENRY, a citizen of the United States,residing at Hope, in the county of Hempstead and State of Arkansas, haveinvented a new and useful Shock-Absorber, of which the following is aspecification.

The present invention relates to improvements in shock absorbers, oneobject of the present invention being the provision of a device which isreadily adapted to be attached to automobiles now in use, the sameconstituting an attaching and supporting means for a tension spring, fordisposition one to each spring of the motor car to limit the recoilthereof and produce the necessary cushion effect.

With the foregoing and other objects in view which will appear as thedescription proceeds, the invention resides in the combination andarrangement of parts and in the details of construction hereinafterdescribed and claimed, it being understood that changes in the preciseembodiment of the invention herein disclosed can be made within thescope of what is claimed without departing from the spirit of theinvention.

In the drawings-Figure 1 is one view illustrating the relation of thepresent shock absorber to the forward spring of a motor car, and to thattype of car known as the Ford automobile. Fig. 2 is a similar view takenfrom the left side of the device as shown in Fig. 1. Fig. 3 is a viewsimilar to Fig. 1 showing the present device applied to the rear springof a Ford automobile. Fig. 4 is a side elevation taken from the leftside as viewed in Fig. 3.

Referring to the drawings, and more particularly to Figs. 1 and 2thereof, the numeral 1 designates the front axle and 2 the front springof the motor car. This spring is attached in the usual mannerto thejournaling sleeve 8 for the crank shaft S of an explosion engine (notshown) and surrounding the crank shaft to the rear of the spring 2 is achannel iron or plate 3, so that the plate 41 which has oppositelyextending apertured arms may rest thereupon, as viewed in Figs. 1 and 2so that the metal bail 5 may be attached thereto by means of the nuts 6.Swingingly connected to the bail and depending therefrom by means of theconnection at 7 thereto, is a tension spring 8, whose eye 9 is attachedto the eye bolt 10 adjustably connected to the lug 11 of the plate 12,said plate 12 being attached by means of the bail-shaped member 13 andthe nut 14 to the axle 1. It will thus be seen that any recoil action ofthe spring or movement upward, is taken care of by the spring 8 whichrelieves the jar on such occasions.

In the form shown in Figs. 3 and 4, the installation is practicallyreversed from that shown in Figs. 1 and 2, to properly connect the sameto operate upon the rear spring 16, the same being connected to the rearspring 16 and to the tube 15, which leads to and is carried by thedifferential and rear axle casing of the motor car. In this instance,

the bail-shaped member 17 surrounds the spring 16 and by means of'thenuts 19 hold the plate 18 thereto, the lug 20 being disposed to carrythe eye bolt 21 which in turn is connected to the terminal 22 of thetension spring 23, the other terminal 24 of such spring being heldbetween the apertured lugs 25 of the clamping band 26 by means.

of the bolt 27. This clamping band 26 is adjusted upon the tube 15 tothe front of the differential casing 28, in such a position as tonormally hold the spring 23 in a vertical position and in such aposition as to take care of the recoil action of the spring 16, thuslessening the rebound and the shock occasioned thereby.

From the foregoing description, it will be evident that thisconstruction of shock absorber is readily applied to the Fordautomobile, and to each spring thereof, and consequently to the completecar.

WVhat is claimed is: The combination with a crank shaft supportingsleeve, a leaf spring and the front axle of a motor car,'of a shockabsorber for the spring including a channeled plate re-iiing upon thespring and having the edges thereof disposed upwardly and astride thesleeve, two clamping bails surrounding the spring, one at each side ofthe sleeve for securing the plate to the spring, a plate having a curvedportion to rest upon the sleeve from above with its ends resting uponthe edges of the sides of'the channel plate, such ends of such platebeing extended beyond iihanne]. plate and apertured,

her having its terminals atpemured ends of the second ing having oneterminal U-shaped member, and *ng the other terminal of to the axle Intestimony as my own, I hr ture 1n the p1 V Witnesses
